&lt;p&gt;&lt;b&gt;新規ページ&lt;/b&gt;&lt;/p&gt;&lt;div&gt;[[Category:Network sharing]]&lt;br /&gt;
Kerberos is one of the few security mechanisms available for NFS. It provides strong per-user authentication, strong data encryption, and (with NFSv4) removes the requirement for matching UIDs/GIDs between client and server.&lt;br /&gt;
&lt;br /&gt;
NFSv4 is recommended for Kerberos. Although it is possible to enable Kerberos in NFSv3, it will not provide 100% coverage as the auxiliary NFSv3 protocols (e.g. the &amp;quot;mount&amp;quot; protocol) remain insecure, and the lack of idmapping in NFSv3 severely reduces the usability of Kerberos as well.&lt;br /&gt;
&lt;br /&gt;
== Prerequisites ==&lt;br /&gt;
&lt;br /&gt;
Kerberos requires a &amp;#039;&amp;#039;&amp;#039;KDC&amp;#039;&amp;#039;&amp;#039; (Key Distribution Center) service to be running somewhere. The {{ic|krb5-kdc.service}} that comes with MIT Kerberos ({{Pkg|krb5}}) is a good option for small setups that do not warrant the complexity of Active Directory or FreeIPA. The second option is Heimdal, found on some BSDs and as {{AUR|heimdal}} on Arch.&lt;br /&gt;
&lt;br /&gt;
NFSv4 &amp;#039;&amp;#039;&amp;#039;idmapping&amp;#039;&amp;#039;&amp;#039; becomes much more important to have with Kerberos. Both the server and the clients should have the same idmapping domain configured: &lt;br /&gt;
&lt;br /&gt;
{{hc|/etc/idmapd.conf|2=&lt;br /&gt;
[General]&lt;br /&gt;
Domain = example.com&lt;br /&gt;
}}&lt;br /&gt;
&lt;br /&gt;
== Server configuration ==&lt;br /&gt;
&lt;br /&gt;
Each NFS server needs a Kerberos principal for {{ic|nfs/&amp;#039;&amp;#039;server.fqdn&amp;#039;&amp;#039;}} to be created on the KDC, and its keys added to the server&amp;#039;s {{ic|/etc/krb5.keytab}}. &lt;br /&gt;
&lt;br /&gt;
{{Note|&lt;br /&gt;
{{Expansion|Why?}}&lt;br /&gt;
It is recommended to &amp;#039;&amp;#039;also&amp;#039;&amp;#039; have the standard {{ic|host/}} principal there as well, for other purposes.&lt;br /&gt;
}}&lt;br /&gt;
&lt;br /&gt;
 fileserv# kadmin -p frob/admin&lt;br /&gt;
 Password for frob/admin@EXAMPLE.COM: *********&lt;br /&gt;
 kadmin:  addprinc -nokey nfs/fs.example.com&lt;br /&gt;
 kadmin:  ktadd nfs/fs.example.com&lt;br /&gt;
&lt;br /&gt;
{{ic|gssproxy.service}} must be [[enable]]d and [[start]]ed on the server. &lt;br /&gt;
&lt;br /&gt;
{{Tip|Earlier systems used {{ic|rpc.svcgssd}}, but it is no longer present in modern nfs-utils and has been fully superseded by gssproxy.}}&lt;br /&gt;
&lt;br /&gt;
gssproxy comes pre-configured with NFS server support (the {{ic|/etc/gssproxy/24-nfs-server.conf}} file is part of the standard package) and does not need any tweaking, other than placing the NFS service keytab in the standard location.&lt;br /&gt;
&lt;br /&gt;
Your {{ic|/etc/exports}} should offer the Kerberos authentication flavors in the {{ic|1=sec=}} option:&lt;br /&gt;
&lt;br /&gt;
 /home    *(rw,sec=krb5p)&lt;br /&gt;
 /usr     10.147.0.0/16(rw,sec=krb5p:krb5i:krb5:sys) *(rw,sec=krb5p)&lt;br /&gt;
&lt;br /&gt;
{{Note|Do not use the obsolete {{ic|gss/krb5p(...)}} syntax. It still works, but you should not be using it anymore.}}&lt;br /&gt;
&lt;br /&gt;
The available flavors are:&lt;br /&gt;
&lt;br /&gt;
* {{ic|krb5p}} provides &amp;#039;privacy&amp;#039; (Kerberos-based encryption). It is sufficiently secure to be used over Internet, but might provide poor throughput over a LAN – consider using {{ic|krb5}} inside RPC-with-TLS instead.&lt;br /&gt;
* {{ic|krb5i}} provides &amp;#039;integrity&amp;#039; (Kerberos-based MAC) but &amp;#039;&amp;#039;not&amp;#039;&amp;#039; encryption. It might be useful for serving static data as it still protects against packet tampering.&lt;br /&gt;
* {{ic|krb5}} provides &amp;#039;&amp;#039;only&amp;#039;&amp;#039; authentication, without data integrity or encryption. It is a good choice if you have RPC-over-TLS enabled via {{ic|1=xprtsec=}} &amp;#039;&amp;#039;or&amp;#039;&amp;#039; if Kerberos is being run over an otherwise &amp;quot;secure&amp;quot; LAN (e.g. over a WireGuard tunnel), but certainly not in the clear over public networks.&lt;br /&gt;
* {{ic|sys}} is the traditional UID-based (non-Kerberos) NFS security mode.&lt;br /&gt;
&lt;br /&gt;
== Client configuration ==&lt;br /&gt;
&lt;br /&gt;
In addition to users, each NFS client should have a &amp;#039;&amp;#039;machine&amp;#039;&amp;#039; Kerberos principal in {{ic|/etc/krb5.keytab}}, which will be used in situations where user Kerberos tickets are not yet available – in particular, it will be needed to actually mount the filesystem at boot time before any users have logged in yet (or if mounting is done via autofs). More generally, all operations done &amp;quot;as root&amp;quot; will be authenticated as the machine principal.&lt;br /&gt;
&lt;br /&gt;
{{Tip|The machine identity is also mandatory for some internal NFS operations if NFSv4.0 or NFSv4.1 are used, although no longer mandatory in NFSv4.2.}}&lt;br /&gt;
&lt;br /&gt;
Unlike in the server case, the client machine does not need an {{ic|nfs/}} principal specifically – it is enough to have the generic {{ic|host/&amp;#039;&amp;#039;the.fqdn&amp;#039;&amp;#039;}} principal. (See the rpc.gssd manual page for what it looks for.)&lt;br /&gt;
&lt;br /&gt;
The client must have {{ic|rpc-gssd.service}} active (i.e. the {{ic|rpc.gssd}} daemon).&lt;br /&gt;
&lt;br /&gt;
Options used when mounting the filesystems are very similar to the options used in {{ic|/etc/exports}}; you can specify one or more flavors using the {{ic|1=sec=}} option. Although the client will automatically use the strongest mode offered, it is nevertheless recommended to explicitly require e.g. {{ic|1=sec=krb5p}} to prevent downgrade attacks.&lt;br /&gt;
&lt;br /&gt;
Once the filesystem has been mounted, root may already access it (using the machine&amp;#039;s Kerberos credentials), but &amp;#039;&amp;#039;&amp;#039;every&amp;#039;&amp;#039;&amp;#039; non-root user needs their own Kerberos tickets to be present. This means either having the user manually run {{ic|kinit}} for themselves, or setting up {{Pkg|pam-krb5}} to acquire tickets during login (which only works for password-based logins), or using {{ic|gssproxy}} or {{man|1|k5start|url=https://manned.org/k5start.1}} (from {{AUR|kstart}}) to acquire tickets from a keytab file. &lt;br /&gt;
&lt;br /&gt;
{{Tip|You will likely need to set up k5start to &amp;#039;&amp;#039;renew&amp;#039;&amp;#039; tickets as they expire a few hours after being acquired.}}&lt;/div&gt;</summary>
